I have a set of davits that are rated at 8k lifting. I want to lift my Hunter 22 to clean the bottom but am not sure how to rig it. I have a copy of a old Hunter ad that shows a 22 being lifted with davits. The davits are connected to the boat via the bow and stern cleats. They look strong enough but ???? Has anyone done this????
Lifting a 22 with davits...

HMMM...
I think we might need a bit more information. "Davits" are usually associated with lifting a small tender/inflatable, or other such small boat up behind a larger vessel. I would not consider lifting any 22 foot sailboat by its "bow and stern cleats". These cleats are not meant to sustain those type of loads.

Davits
Lots of people down here have davits in their yards (if they live on the water)and they are mostly used to lift power boats (up to the rating of the davits). Mine are rated to pick up 8000 pounds and I have picked boats in excess of 4000 pounds with no problem. I had thought of making up a set of straps such as they use in boatyards but then saw the picture in the old Hunter ad showing the 22 being lifted. It sure looks like they are using the cleats but I thought like you ...... that's a lot of weight on those cleats. I guess I should go ask Hunter. Thanks for the reply

Lifting using cleats
I seriously doubt that the ad you speak of shows an H22 being lifted out of the water by it's bow and stern cleats. Technically speaking assuming your vessel has OEM cleats, they are made of zinc which is a very weak metal not to mention that they are hollow. As it has aged it's only gotten weaker. Although they are through bolted, the OEM bolts are #10 machine screws. Most all marine hardware is 316 stainless steel which again is extremely soft. Ever notice how easy it is to round out a phillips head with a screwdriver in one. It's soft stuff. The tensile (breaking strength) of these screws are around 600 pounds. Then there's the wood backing plate to each cleat that nots gotten any stronger either which also needs consideration. Personally, living along the Gulf coast and finding myself having to regularly anchor my boat out to ride out a hurricane or tropical storm, I replaced all my cleats to solid stainless steel cleats using larger bolts and thats just for anchoring and still wouldn't contemplate lifting it by them much less putting myself under it to do any work. Bottom line, I certainly wouldn't attempt it and wouldn't advise ANYBODY to do it either. There are other ways to go about it. 1) go to a boatyard and have a haulout. 2) borrow a trailer 3) drop your mast and use a friends powerboat lift 4) get in shallow water and water and wait for the tide to go out and leave it dry.
